In fact, it is rpn. And - no wonder - in terms of speed and simplicity, a rpn calculator outperformes the normal one - no brackets and no operator order needed.
Its just that we are not used to it ...
Same problem like with smalltalk - not in every situation the better design wins.

In fact, it is rpn.

Is it? My impression is it is something halfway. Functions (methods?) can have operands on the left and right sides, if I recall correctly from some reading many years back trying to grok it (finding it confusing, I gave up). In a true RPN language (like FORTH or PostScript), operators always after all operands come.
